The corporation had failed to settle the club's debts by a deadline of December 28, causing the deal to be invalidated and leaving Wisla in a state of financial limbo.

BIG NEWS from this morning: @jarokrolewski the passionate IT entrepreneur, KUBA BŁASZCZYKOWSKI and a third yet publicly unnamed person will contribute 1.3mln PLN (300K€) of their OWN money, so that the outstanding players' wages can be paid. This is a lifeline for Wisla. Respect

However, Blaszczykowski, who represented the club between 2005 and 2007 before joining Borussia Dortmund for a reported fee of €3m, has, along with two other investors, given the club a lifeline out of his own pocket.

Additionally, he has agreed to join their ranks without a wage in an admirable show of loyalty.

The money provided will help the club pay outstanding wages and give the hierarchy time to negotiate a possible takeover with any interested parties.

Dortmund have lauded their former player's generosity, hailing his loyalty - a trait the club experienced first-hand following nine years of faithful service, with Blaszczykowski often playing out of position wherever needed to help the team.
